PORTABLE FIRE-ESCAPE.

Specification of Letters Patent.

Patented Sept. 30, 1913.

Improvements in Portable Fire-Escapes, of

which the following is a specification.

Our lnventlon relates to an improvement in portable fire escapes; and the'object-s of our improvements are; first, to'provide a portable fire escape which may be readily adjusted by the user; second, to provide a fire escape that may be operated by the user in any building, and at such speed as he may desire; and third, to provide a fire escape that may be used by the operator in an emergency without assistance from others; and other objects which will more fully appear from the specification.

We attain these objects by the use of the mechanisms illustrated in the accompanying drawings, in which Figure 1 is a perspectiveview' of the reel with steel tape attached; Fig. 2 is a perspective view showing the interior of the drum and brake, with the reel, and the plate shown in Fig. 6 removed; Fig. 3 is a perspective view of the exterior of thede'vice; Fig. 4 is a conventional view showing the attachment of the device to a window; Fig. 5 is a cross sectional detail view of a desirable method of constructing the brake lever; and Fig. 6 is a view of the plate that incloses the device within the drum.

Similar numerals refer to similar parts throughout the several drawings.

A drum 8 is provided with a slot 9 and eye 14 which are preferably located on the same side of the center of the drum. The head of the drum is provided with slots 11, and on the exterior side of which slots are elements 12 adapted to receive a bolt 13. The brake levers 15, two in number, are pivotally attached by the bolt 13, and have extended elements 15 adapted to receive the brake 21 on which may be placed any friction material 22. The exterior end 15 of each brake lever is screw threaded, one right hand and the other left hand, and adapted to receive the right and left handed screw threaded bar 16, which bar 16 has an extension 16 to which is attached the handle 17. In order to prevent an operator of the device, in the excitement consequent on its use as a fire escape, from releasing the brake too much, a double-nut 30, constituting a fixed or set nut, is provided so that the levers may be adjusted to cause close bearing upon the reel, as hereinafter described, and so that it may be adjusted from time to time as desired and thereby prevent an operator from loosening the brake too much.

We have shown another form of constructin -the head of each lever 15 in Fig. 5, whic may be used without departure from the principle of our invention. The top of each lever 15, instead of being screw threaded, is provided with a rounded head 25. The screw threaded nut 26, one for each side of the right and left handed screw threaded bar, is provided with arms 28 which inclose a large portion of the head 25, and suflicient motion is permitted so that the screw threaded nut 26 may at all times be at right angles to the threads upon the bar. The head 25 is provided with a hole adapted to receive a bolt which is provided with washers 2'? on each side so that when the drum 8 has been placed over the head 25 the arms are held in position over the head 25. While the device may be operated' by means of the ends of the brake levers being screw threaded as shown in Fig;

3, in order to avoid cramping on the screw threaded bar, we have provided the above construction.

- The reel 4 has attached thereto the steel tape 1, by rivets 3, but any other style of tape may be used. The spindle 6 operates in the bearing 7 and the other end 24 in the bearing 24. The spindle end 24 may be flattened to provide means for winding up the tape by means of a wrench. The hook 2 is attached to the free end of the steel tape. The reel being fitted into the drum 8 with the tape passing through the aperture 9, the plate 23 is attached to the outside of the drum 8. The interior of the rim of the reel 4 is provided with a space 5 adapted to receive the friction bearing 22 of the brake.

The device being assembled in all its parts, it may be attached to any hook 28, or other means, on a window 19, or elsewhere, by means of the hook 2. The operator adjusts himself in the loop 23, or any other harness which may be desired, attached to the eye 14. The operator by using the handle 17 may stop the reel or may fix the speed at which he will descend. The whole device descends with the operator, and when the operator has descended to the ground he may break the tape and still have the device; in which may be placed a new tape.

The device is so compact that it may easily be carried in an ordinary hand bag; arid is readily attachable to and usable in any building.

We claim 1. In a portable fire escape of the character described, a drum provided with slots therein; a reel adjusted within said drum; a tape attached to said reel at one end and the other end of said tape provided with a hook for attaching purposes; brake levers attached pivotally to said drum and extending to the interior thereof and provided with brake shoes on the interior side, adapted to engage the interior of said reel, the exterior end of each of said brake levers screw threaded; a screw threaded bar adapted to engage the exterior ends of said brake levers and provided with a handle, ada ted to operate said brake levers, all as descr1 ed.

2. In a portable fire escape of thecharacter described a reel inclosed in a drum having provided on the interior surface of said reel a space adapted for the operation of a brake; a tape attached to said reel and extending outside of said drum and provided with a hook adapted to attach to any object; brake levers attached pivotally to said drum, and adapted to operate on the interior side of said reel; a right and left threaded bar adapted to operate in the exterior ends of said brake lever and the same Copies of this patent may be obtained for being provided with screw threads adapted 40 said reel, the exterior end of said levers provided with a ball head; a nut adjustable over said ball head of said lever and adapted to be held in position by bolt with wash 0 ers; a right and left screw threaded baradapted to operate said nuts, all as described. V

4:. In a portable fire escape of the character described, a drum provided with slots therein; a reel adjusted within said drum; a tape attached tocsaid reel at one end and the other end of said tape provided with a hookfor attaching purposes; brake levers attached pivotally to said drum and extending to the interior thereof and provided with brake shoes on the interior side, adapted to engage the interior of said reel, the exterior end of each of said'brake levers screw threaded; a screw threaded bar adapted to engage the exterior ends of said brake levers and provided with a handle, adapted to operate said brake levers ;'a double nut on the free end of said screw threaded bar 7 adapted to adjust the extent of release of said brake levers; all as described.
